SCREEN.

Specification of Letters Patent.

Patented Mar. 26, 1918.

Application filed August 7,1916. Serial No. 113,567.

12; all 70/101. it may concern.

Be it known that I, \ViLLIAM S'rnonn, a citizen of the United States, residing at Linden'Heights, in the county of Franklin and State of Ohio, have invented a new and useful Screen, of which the following is a specification.

This invention relates to metal screens, one of its objects bein to provide a screen in which the wire fabric can be renewed readily without requiring the services of a skilled. mechanic.

A further object is to provide a screen frame, the stiles and rails of which are connectedat the corners of the frame by an invisible connection.

Another object'is to provide a screen, the parts of which can be assembled readily without requiring the services of an expert.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, witlr out departing from the spirit of the invention.

In the accompanying drawingsthc preferred form of the invention has been shown.

In said drawings Figure 1 is an elevation of a screen having the present improvements combined therewith.

Fig. 2 is an enlarged elevation of the outer side of one corner portion of the screen.

Fig. 3 is a view similar to Fig. 2 but with the clamping strip and the fabric removed.

Fig. 4 is an enlarged section on line A-B Fig. 3.

Fig. 5 is a section on line C-D Fig. 2, the fabric being removed.

Fig. 6 is an enlarged section on line lCF Fig. 1.

Fig. is an enlarged section through a portion of one of the stiles oi the screen frame. said section being on the line G-H Fig. 3..

Fi {i a perspective view of one of the corner plates.

Referring to the tiguz" reference 1 designates the frame and 2 and 3 designate the top and bottom rails respectively. Each of these stiles and rails is formed with mitered ends and each of them is formed of a channeled strip of sheet metal, the open faces of the strips bein located at the outer side of the screen, \vhi e a longitudinal bead 4 is pressed inwardly along the inner side of each strip. One of the stiles may be provided with bow springs 6 secured thereto and constituting means for engaging the window or door casmg in which the screen is mounted.

Each of the stiles and rails has a flange 7 extending inwardly i inner edge of the outer side thereof. this. flange merging into an inwardly extending obliquely disposed apron 8 projecting into the channel strip of which the rail or stile is formed. Another flange 9 is formed along that side of the open face of the channel strip remote from the flange 7 and this flange is rounded as shown warticularly in F ig. 4-, its free edge lying close to the ad jacent wall of the strip.

For the purpose of holding together the rails and stiles at their ends. corner plates 10 are employed. Each of these corner plates is substantially L-shaped and has a head 11 rolled thcreinto along the longitudinal c'entcr thereof, this head being adapted to straddle the heads formed upon the meeting members 01 the screen. The plates 10 fit snugly within the meeting channel strips and have flanges 12'extcnding along the longitudinal edges thereof, the flanges along the outer edges of the plates being adapted to engage between the outer walls of the channel strips and the flanges 9, while the rmnaining flanges on the corner plates are adapted to fit between the inner walls of the channel strips and the aprons 8. The plates can be assembled with the channel strips by slipping said corner plates longitudinally into engagement with the end portions of the stiles and rails until the angle portions of the corner plates fit snugly within the meeting ends of the rails and stiles. After the parts have thus been assembled. an ordinary nail punch can 1 used for the purpose of forming depressions, such as shown at 13, in the stiles and rails and within the corner plates. After these depressions have been struck into the parts, it will he obviously a difficult matter to pull the parts out of engagement with each other.

For the purpose of securing a screen 'fabtherefrom from thc' edge of the while the opposed against the outer sideof i so as to hook upon the inner ric, such as shown at 14, to the screen, a series of holding strips are employed. Each of these strips has mitered ends and is formed of sheet metal, said strips being provided along their longitudinal edges, with substantially parallel inclined flanges 15 while the intermediate portion 16 of each strip is preferably formed with a longitudinal grout-"e or depression 17. Flanges 15 are adapted to be received within the channeled stiles and rails and are so proportioned that when they are forced thereinto, one flange of each of the holding strips will bind against a portion of the screen fabric, portion of each of the holding stri s will yieldingly engage the flange 9. Tl iis flange, by reason of its peculiar rounded formation, not only serves as a spring for binding the inserted holding strip against the inserted portion of the wire fabric so as to clamp said fabric securelv against the apron 8, ut also acts as a 100 to prevent accidental withdrawal of the holding stri from the channel strip. While one of the anges 15 of each strip serves as a clamping member, the other flange 15 M15 as a means for limiti the movement of the clamping'stri inwar 1y into the stile or red on aged there y.

be holding strips are ada ted to fit tightly together at their ends at one of them is preferably bent outwardly to a slight extent as shown at 18 so that a knife or other like device can be forced under said strip thus to enable the strip to be out of the channel strip engaged there and to give access to the remaining ho ding strips which can likewise be removed.

The springs 6 broadl considered do not constitute any part of t 0 present invention but have been fully disclosed in my Patent No. 1,010,700 issued to me on December 5, 19.11, and I merely utilize the same as a means for holding the screen in its guides, it being possible by ulling laterally on the screen, to place the prings 6 under compression and disengage one stile from the guide of the window casing.

One of the means for fastening a s rin 6 o the device has been illustrate in etain Fig. 7. One end portion of the spring is engaged b one end of a holdingstrip 19 wrapped tnerearound and which strips bears the stile 1 and is bent inwardl ange 9, the hooked portion of 'the stri 19 being sho m at 20. Thus when the hol ing strip1 16 is pressed into position it will engage e inwardly extending portion pf t e hooked strip 19 as shown in Fi i lifts 21 can be placed wherever desired upon the screen frame and in Fig. 1 two of these lifts have been shown upon the bottom portion of the frame. These lifts, which ressed are of any suitable form, are pivotnlly mounted in eyes 29 formed by the inlermediate portions of a metal strip 23. This strip has two arms 24 and 25, the arm extending across the inner face of the stile and terminating in a lip 26 engaging the vertical face of the channel member 3, while the other arm 2.3 extends along the flange 7 and terminates in a hook 27 which engages the inner edge of the apron 8.

Should it be desired to arrange hinges uponihc screen frame, one of which has been indicated at 28, the arrangement illustrated in Fig. 6 could be employed. As shown in this figure one of the leaves of the hinge 28 is provided with two arms 29 and 30, the arm 29 extending inwardly along the flange 9 and terminating in a hook 31 which engages the inner end of the flange: The other arm 30 extends along the free outer faces of the stile and terminates in a lip 32 which engages the flange 7.

In all of the structures shown the parts employed for holding the springs, lifts and hinges can be readily slipped longitudinally into position before the parts of the frame have been assembled and after they have thus been positioned, they can be secured by striking depressions in the metal with a nail punch or the like.

By providing the heads 4 which project. into and fit snugl within the beads 11, a rigid joint is pro need at each corner, the interfittin heads 4 and '11, the flanges l2 and the anges 7 and 9 all cooperating to produce a rigid frame. The depressions 13 'serve to prevent the stiles and rails from sli pin oil, of the corner plates.

hi e the frame herein described is especially designed for use in connection with wire fabric, it is to be understood that the same can also be used for holding any other kind of fabric, such as canvas or the like.

What is claimed is 1. A window screen including a frame made up of abutting mitered channel strips, each strip having an inwardly directed ob liquely disposed apron along its inner side and an inwardly 'rojeeting longitudinally extcndin locking ange along its outer side, a fabric liming its edge portions inscrtible between the flanges in said channel strips, and a clampirlg strip insertible into the channel st ri s and having meeting mite-red ends, each -e amping strip including a flange cooperating with tie a mu to bind upon a portion ofthe screen in ric, and aflange for limiting the movement of the clamping strip into the channel stri 2. A screen including a frame made up of mitered meeting channel strips, each strip haying one face open and provided along one side with an inwardly extending obliruely disposed apron and along its other s1 0 with an inwardly extending locking 1 flan means fittedwithin the end ortions of t e channel strips for'securing t mm together, a screen fabric haying its edge portions extending into the channel strips, and holding strips insertible into the open faces of the channel strips, said holding strips having obliquely disposed flanges coiiperating with the a mo to bind upon the inserted portions of the screen fabric and having means for limiting the inward movement of the holdin strips relative to the channel strips, saidaicking flan s cooperating with the apron to secure the olding strips within the channel strips.

3. A screen including a frame made up of mitered meeting channel strips, each strip having-one face-open and provided along one side with ah inwardl extending obliguely disposed apron and along its other si e with an inwardly extendin locking flange, means fitted within the en portions pf the channel strips for securing them together, a screen fabric having its edge portions extending into the channel strips, and holding strips msertible into the open faces of the channel strips, said holding strips having obliquely disposed flanges coiilperating with the apron to bind upon t e inserted portions of the screen fabric and having means for limiting the inward movement of the holding strips relative to the channel stri 8, said locking flan es 006 erating with t e apron to secure t e hol in stri s within the channel strips, one of sai hol ing strips havinf an offset end portion. In testimony that claim the foregoing as my own, I have hereto ailixed my signature in the presence of two witnesses.
